Problems solved by technology

[0005] 1) The power distribution equipment is not connected to the system bus, so the system has no online monitoring function and cannot be independently measured and controlled when it is in orbit;
[0006] 2) The circuit is complicated and the system structure is huge, which may affect the reliability of the system;
[0007] 3) Large power consumption and volume;
[0008] 4) Requires software to work together

Description

technical field [0001] The invention relates to a small power distribution measurement and control system applicable to satellites. Background technique [0002] In a conventional satellite measurement and control system, it is often necessary to collect various analog signals and digital signals and process them accordingly. For example, in the distribution equipment, there are many various analog signals that need to be collected (such as the power supply voltage range of each power supply of each powered device and the corresponding current usage of the power supply, etc.), digital signals (such as power supply Switch status monitoring), and at the same time, it is necessary to open and close the relays in the distribution equipment, so as to complete the power-on and power-off functions of the load. [0003] In the existing satellite system design, power distribution measurement and control is generally realized through conventional ground telemetry and remote control c...
